Engineering related to wheeled guide handles for the visually-impaired Art

In the past, wheeled guide handles for the visually impaired were ordinary foldable handles without wheels, which had disadvantages due to inconvenient use and no core to create a wide frontal space to provide awareness of obstacles. In addition, older wheeled guide handles for the visually impaired had no electronic equipment to assist the visually- impaired in providing safety, which made it easy for accidents to happen.

Description of Embodiments

The wheeled guide handle for the visually impaired has the lower end of the handle equipped with wheels that function to guide the visually impaired. The wheels are housed with casing and at least one position of the casing is equipped with at least one wheel.

The purpose of this invention is to have a wheeled guide handle for the visually impaired to facilitate the visually impaired in learning about obstacles in a way that is easy, convenient and safe to use with a set of electronic equipment for assisting the visually impaired.

Full Disclosure of the Invention

Figure 1 and Figure 2 show the components of the wheeled guide handle for the visually impaired with characteristics consisting of the following:

The handle (10) made from wood, plastic or metal, which functions to support handling by the visually impaired.

The lower end of the handle (10) is equipped with wheels (20) and performs the function of guiding the visually impaired for convenient use.

The wheels (20) are housed inside the casing (30). One position of the casing (30) is equipped with at least one wheel (20). The casing (30) is atached to the horizontal axle (31) and creates a frontal surface to create space for hiting obstacles to allow the visually impaired to learn about obstacles in front.

The horizontal axle (31) has a specified length which creates space for installing at least one wheel (20) such as for installing two wheels or four wheels, etc., in order to create a casing (30) model with wheels (20) that can be installed and removed to be suitable for use.

The wheels (20) can rotate for 360 degrees to create 360-degree directional guidance with a mechanism for locking wheels (20).

One position of the handle (10) has a hook (21) for hanging items or one position of the handle (10) is equipped with a basket (22). One position of the basket (22) is the casing fitted to one position of the handle (10) in order to install the basket for holding items.

Figure 3 shows an image of the handle (10) with a mechanism for adjusting length with the small-diameter handle (11) and the large-diameter handle (12) that slide in and out together with a locking mechanism that can be selected by twisting, pinning or turning, etc.

Or the small-diameter handle (11) and the large-diameter handle (12) may fold together with a rotating point (not displayed) for folding the handle (10).

One position of the handle (10) is equipped with electronic equipment for assisting the visually impaired with characteristics consisting of:

A sensor (41) which functions to provide information on distance to the obstacle. The sensor (41) is connected to the processing unit (40) and functions to report the distance to the obstacle to the processing unit (40). Once the processing unit (40) receives data on the obstacle, the processing unit will send data to the speaker (42) to provide an audio rhythm show distance between the sensor (41) and the obstacle.

The camera (50) functions to detect images. The camera (50) is connected to the processing unit (40) and functions to report images of obstacles to the processing unit (40). Once the processing unit (40) receives images of obstacles, the processing unit will process data and match images to prefabricated data to determine the obstacles in the image such as electricity posts, cars, people, trees, walls and holes, etc. The processing unit (40) will send processed data to the speaker (42) to provide audio information on the obstacle in the image such as electricity posts, cars, people, trees, walls and holes, etc.
